PIPE CLEANER.

Application filed April 5, 1922. Serial No. 549,807.

To all whom it may concern:

Be it known that 1, JOHN S. Arum, a citizen of the United 'States,residing at Denver, in the county of Denver and'State of Colorado, haveinvented certain new and useful Improvements in Pipe Cleaners, of whichthe following is a specification.

My invention relates to tobacco pipe cleaners and its object is toprovide a device of very simple construction which when turned insidethe bowl of a tobacco pipe, will in one operation, loosen all residue ofthe burnt tobacco usually adhering in the bottom of the bowl after thepipe has been smoked, and withdraw the loosened matter through the mouthof the same, and which at the same time will even and remove theincrustation on the interior surface of the bowl.

Another object of the invention is to provide a tool of the abovedescribed character which can be folded when not in use and may becarried loose in the pocket or at the end of a watch or keyring chain.

With the above objects in view my invention consists in the novelconstruction illustrated in the accompanying drawings in the variousviews of which like parts are similarly designated and in which- Figure1 represents an elevation of my improved pipe cleaner in the openposition;

Figure 2, an edge view of the same, looking in the direction of thearrow 2 in Figure 1;

Figure 3, an elevation of the device in its closed position;

Figure l, a transverse section of the blade of the cleaner taken on theline lel, Figure 1 and drawn to an exaggerated scale, and

Figure 5, a sectional elevation of the bowl of a tobacco pipe showingthe working end of the cleaner in its operative position with relationthereo.

Referring more specifically to the drawings, my improved pipe cleanerconsists of a flat blade 5 pivoted as at 7 at an end of a two leavedhandle 6 which when the device is not in use, encloses the major portionof the blade and protects the cutting edge thereof.

The handle which in the form shown in the drawings consists of twoleaves 13 and an interposed distance slug 14: at an. end thereof, iscurved in conformity with the blade as will hereinafter be described,and

provided with an aperture 8 for its attach: ment to the chain of a watchor key-ring.

The blade which is preferably made" of tempered steel is of asubstantially uniform width slightly less than the inside diameter of apipe bowl of average size. The blade is sharpened to provide a cuttingor scraping edge 9 and its end is rounded as at 10 in approximatelysemi-circular form to fit the bottom portion of the bowl of a tobaccopipe in which it is inserted.

The rounded end portion of the blade is furthermore bent at the cuttingedge of the same in an auger twist which when the tool is turned insidethe pipe bowl, withdraws the loosened matter toward the mouth thereof.

In the operation of my.imp-ro-ved pipe cleaner, the blade is inserted inthe pipe bowl as illustrated in Figure 5, and turned therein about alongitudinal axis with its cutting edge engaging with the interiorsurface of the bowl.

The rounded and twisted end-portion of the blade loosens and removes thecharred and moistened residue of the burnt tobacco which usually remainsin the bottom of the bowl after the pipe has been used and the cuttingedge of the blade at the same time, evens the carbon incrustation on theinner surface of the bowl and loosens adherent ashes and tobacco.

When subsequently the blade is withdrawn from the bowl, it carries withit all the loosened, matter owing to the auger twist of its rounded endportion.

The auger twist furthermore prevents the loosened matter from enteringthe stem of the pipe and the uniform width of the blade preventsundercutting of the incrustation, as occurs in the use of pipe cleanersat present on the market, and permits of the re moval of all or any partof the incrustation as may be desired.

A single turn of the blade inside the pipe bowl produces a smooth cleanand even surface and frees the opening in the bottom of the bowl fromany obstructive matter which if permitted to remain would hinder thefree passage of the smoke to the stem of the pipe.

It will be apparent that my improved pipe cleaner thus performs in oneoperation the functions of two or more other tools ordinarily requiredto thoroughly clean the bowl of a pipe.

What I claim and desire to secure by Letters Patent is'z' 1. A tobaccopipe cleaner comprising a flat blade having a scraping edge and arounded end which is bent at said edge into an auger twist.

2. A tobacco pipe cleaner comprising a blade of substantially uniformWidth, having a scraping edge and a rounded end Whichis bent at saidedge into an anger twist.

3. A tobacco pipe cleaner comprising a blade having a scraping edge andan end of substantially semi-circular contourwhich is bent at said edgeinto an auger twist.

4. A tobacco pipe cleaner comprising a fiatblade of substantiallyuniform Width having a scraping edge and an end of substantiallysemi-circular contour Which is bent at said edge into an auger twist,

5, A tobacco pipe cleaner comprising a sharp-edged blade having its endrounded to fit the, concavity at the bottom of a pipe bowl at one sidethereof, and bent into an auger twist to provide a scoop for theWithdrawal of loose matter from the .bowl.

In testimonywhereof I'haVe affixed signature.
